chlorine and peracetic acid was determined using a free and total photometer (HI 93734‚ Hanna Instruments‚ Eibar‚ Spain). ORP and pH were determined using a pH/ion/conductivity meter (Model GLP-22‚ Crison)‚ with a pH electrode (Crison‚ 52-01) or an ORP electrode (Crison‚ platinum Ag/AgCl electrode 52-61). In addition the microbial load of each washing solution after treatment was evaluated. To carry out such determinations‚ 1 mL of each washing solution was added to 9 mL of buffered peptone water (BPW‚ Oxoid)

than water‚ so it will sink to the bottom of the well. The gel is then covered with a buffer solution that can carry electric current‚ and electrodes are placed at each end of the gel and connected to a power supply. Because DNA is negatively charged (each nucleotide has a negatively charged phosphate attached to it)‚ it will move toward the positive electrode. Larger molecules move through the agarose more slowly‚ while smaller ones can slip through the pores faster. So‚ the fragments wind up

RENEWABLE ENERGY RESOURCES ABSTRACT The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels (i.e.‚ coal‚ petroleum and natural gas) and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy

This patent became the basis for the monopoly held in neon lighting by his company‚ Claude Neon Lights for neon signs throughout the early 1930’s. -Claude had solved the two technical problems that substantially shortened

<b>INTRODUCTION</b><br><br>The human body is divided into many different parts called organs. All of the parts are controlled by an organ called the brain‚ which is located in the head. The brain weighs about 2.75 pounds‚ and has a whitish-pink appearance. The brain is made up of many cells‚ and is the control centre of the body. The brain flashes messages out to all the other parts of the body. The messages travel in very fine threads called nerves. The nerves and the brain make up a system somewhat

tape records your heart’s activity continuously for 24 to 48 hours or longer depending on the monitor used. The device is the size of a small camera. It has wires with electrodes that attach to your skin. Make sure to tell your technician if you are allergic to tape or adhesive since they will use tape to make sure the electrodes stay in place. Getting regular EKG’s let your doctor look at your heart’s activity. But abnormal heart rhythms and cardiac symptoms may come and go. That’s why your doctor

Electrolysis of water Use a U-tube with electrodes at each end‚ connected to a battery. Fill the U-tube with water. Turning on the battery‚ observe the results at each electrode. Next‚ test for hydrogen and oxygen gas produced at each end of the tube. 5. Burning magnesium Place magnesium ribbon in a clean crucible (on a clay triangle above a Bunsen burner)

except that you placed your gel in the electrophoresis chamber with the wells containing the DNA next to the red electrode instead of the black‚ what would happen? Explain. The DNA would flow backwards instead of forward from its well‚ meaning that the DNA would basically pile onto one-another since the wells are at the very end of the gel. The negative DNA would flow towards the red electrode‚ which is positive. 3. If you have a restriction enzyme that cuts a piece of DNA at two recognition sites
